hard to say something without knowing the diagram.
I could guess there is a 1st stage RF amplifier tube, an IF oscillator an if amplifier and an audio amplifier.
What i would do, is remove the tubes one by one, try to carefully clean them to find what kind of tube they are,
and look up on the internet to find spare.
Assuming the radio fires up, change one tube at time to see if it start playing.....
Edit: forgot to say: a couple of capacitors in the audio section would probably need to be changed as well.
